WRENCH.

Application filed September 8, 1921.

6 To all whom it may concern:

Be it known that we, LYMAN Gnonon RnYNoLns and ARTHUR LYrLn HOLMAN, bothof the city of Toronto, in the county of York, in the Province ofOntario, Canada, have invented certain new and useful improvements inlVrenches, of which the following is the specification.

Our invention relates to improvements in wrenches and the object of theinvention is to devise a wrench with a head portion piv otally connectedto the handle portion whereby the head may be set at different angles tothe handle to admit of the wrench being used on nuts which wouldotherwise be inaccessable thereto. A further object is to provideratchet means between the head and the handle of the wrench whereby thewrench can only be used in one direction i. e. the direction in whichthe pressure on the movable jaw of the head will be in a clownwarddirection thus preventing wear on the slide thereof.

A further object is to provide improved means for pivotally connectingthe head to the handle.

Our invention consists of a wrench constructed and arrangedsubstantially as hereinafter more particularly described and illustratedin the accompanying drawing in which Fig. 1 represents a front elevationof our wrench.

Fig. 2 represents a side view thereof.

Fig. 3 represents a front view partly in scection, and

Fig. 41- represents a cross sectional view thereof showing the means forpivotally connecting the head to the handle.

Like characters of reference indicate corresponding parts in thedifferent views.

1 is the handle of the wrench provided with the bifurcated upper jaws 2and with the vertical orifices 3. at is the head of the wrench havingthe fixed jaw 5 and the movable jaw 6 with the tooth slide 7 operated bythe suitably journalled knurled worm S. 9 is a suitably curved rackformed on the lower end of the head 4:. 10 is a countersunk screw pinextending through'the lower end Serial No. 499,159.

of the head and threaded through theother jaw 2. 11 is a plunger havingthe toothed upper end 12, said plunger inserted through the orifices 3and normally spring-held by the spring 13 against the teeth on the lowerend 9 of the head. 14 is a vertical slot in the plunger 11 and 15 is alever pivotally mounted in the handle 1, the inner end of said leverengaging the lower wall of the slot 14-.

The wrench is actuated as follows:

In order to set the head at a suitable angle relatively to the handle itis merely necessary to ratchet the head on such handle, or in the eventof the head already being swung over at an angle by lifting up the lever15 the plunger 11 will be depressed and the toothed upper end thereofdisengaged from the teeth on the lower end 9 of the head whereby suchhead may be swung into the desired position freely of the handle. Byletting go the lever 15 the spring 13 will restore the plunger into itsoperative position wherein the tooth 12 will engage the required toothon the lower end 9 of the head.

From the above description it will be seen that the wrench can only beoperated in one direction, namely in the direction in which the movablejaw 6 will be pressed downwardly, thus preventing wear on the slide 7.

By threading the end of the screw pin 10 into one of the jaws 2 it willbe seen that any spreading of the bifurcated jaws 2 will be obviated, aswould otherwise occur.

What we claim as our invention is:

A wrench comprising a handle a head pivotally connected to the handleand having an arc-shaped lower portion provided with ratchet teeth, aplunger slidable in a longitudinal orifice in the handle and having atoothed upper end, one of the faces of the tooth being bevelled, aspring normally holding the toothed upper end of the plunger inengagement with one of the ratchet teeth on the head and a leverpivotally mounted in the handle and the inner end thereof engaging aslot in the plunger.
